JBL Boombox 4 portable Bluetooth speaker. 

This latest iteration features significant upgrades over its predecessors, offering powerful sound, robust build quality, and modern connectivity options. 

Key Features and Specifications

Sound: It delivers massive JBL Pro Sound with deep and punchy bass, thanks to two 5-inch woofers, two 0.75-inch tweeters, and three passive radiators. It also includes AI Sound Boost technology, which analyzes music in real-time to adjust sound for less distortion at higher volumes. Users can choose between "Deep Bass" and "Punchy Bass" modes via a button on the top panel or the companion app.

Durability: The speaker has an IP68 rating, making it both waterproof and dustproof.

Battery Life: It offers up to 28 hours of playtime on a single charge, which can be extended to up to 34 hours using the Playtime Boost setting in the app. A key new feature is the replaceable battery pack (sold separately).

Connectivity: It uses Bluetooth 5.4 and supports Auracast, allowing you to connect multiple compatible JBL speakers for a wider sound stage or party mode. It also supports lossless audio playback via its USB-C port.

Design: It is slightly larger than the previous model but is designed to be lighter for easier portability. The product and its packaging incorporate recycled plastic and fabric.
